GHK-Cu 2mg x 60-Capsule Copper Tripeptide Overview
GHK-Cu 2mg x 60-Capsule from Peptide Science is the encapsulated oral-format research preparation of the copper-bound glycyl-L-histidyl-L-lysine tripeptide, supplied at 2 milligrams per capsule in a 60-count sealed bottle for preclinical animal-model oral-bioavailability research on the copper-peptide pathway.
Class and Mechanism in Skin and Bioavailability Research
GHK is the naturally occurring tripeptide Gly-His-Lys present in human plasma; the copper-bound form GHK-Cu binds Cu2+ at the histidine imidazole nitrogen and the C-terminal carboxylate, supplying the cation for copper-dependent enzymatic pathways. Preclinical cell-culture work has characterised the molecule for collagen and decorin synthesis in fibroblasts, modulation of matrix metalloproteinase activity, and antioxidant signalling. The encapsulated oral format supports research on bioavailability and systemic distribution of copper-bound tripeptides via the gastrointestinal route, distinct from the topical and lyophilised-vial formulations also stocked in the catalogue.

Handling and Stability
The copper-bound centre is light-sensitive at long exposure, so the sealed bottle stores in opaque packaging away from direct sunlight. For lyophilised injectable formats, see GHK-Cu 50mg. For topical research formats, see GHK-Cu 200mg Topical or GHK-Cu 1g Topical.
Quality and Shipping
Each batch passes HPLC at greater than 99 percent purity. A Certificate of Analysis accompanies every order. Material is prepared in a US laboratory under ISO 9001:2015-aligned quality systems and dispatched in standard sealed packaging via overnight or two-day courier.
